Arsenal are desperate to find a buyer for Shkodran Mustafi.
Mustafi's struggles this season have led to manager Unai Emery finally calling time on the centre-back's Emirates Stadium career, the club having reportedly tried to flog him every window since he signed in 2016.
BBC journalist David Ornstein told Radio 5 Live: "After the Europa League final, Unai Emery who had always put his faith in Mustafi despite a number of high-profile mistakes, decided that enough was enough with him.
"And he is no longer in favour of keeping him - so he could be sold.
"Arsenal have tried to sell him pretty much every window since they signed him."
